ABSTRACT:
In a friction clutch unit the axial travel of the presser plate with respect to the clutch housing is axially limited. The presser plate is connected for common rotation with the clutch housing by a plurality of tangential leaf spring elements. These leaf spring elements allow axial travel of the presser plate with respect to the clutch housing, when the clutch housing is separated from the respective driving disc. A main spring is provided which is supported on the clutch housing and acts onto the presser plate. This main spring urges the presser plate away from the clutch housing. In order to restrict the travel of the presser plate under the action of the main spring stop elements are provided axially between the spring elements and the clutch housing and tangentially between the two ends of the respective leaf spring elements, namely nearer to that end of the respective leaf spring element which is fixed to the clutch housing. In assembling the friction clutch one can preassemble the presser plate with the leaf springs and thereafter insert the presser plate with the leaf springs into the clutch housing. Hereupon the free ends of the leaf springs are fixed to the clutch housing. The insertion of the presser plate with the leaf springs into the clutch housing requires only an axial movement of the presser plate with respect to the clutch housing along the common axis of the clutch housing and the presser plate.
